|---|---|
| EfiResetCold | Used to induce a system-wide reset. This sets all circuitry within the system to its initial state. This type of reset is asynchronous to system operation and operates withgout regard to cycle boundaries. EfiColdReset is tantamount to a system power cycle. |
| EfiResetWarm | Used to induce a system-wide initialization. The processors are set to their initial state, and pending cycles are not corrupted. If the system does not support this reset type, then an EfiResetCold must be performed. |
| EfiResetShutdown | Used to induce an entry into a power state equivalent to the ACPI G2/S5 or G3 state. If the system does not support this reset type, then when the system is rebooted, it should exhibit the EfiResetCold attributes. |
| EfiResetPlatformSpecific | Used to induce a system-wide reset. The exact type of the reset is defined by the EFI_GUID that follows the Null-terminated Unicode string passed into ResetData. If the platform does not recognize the EFI_GUID in ResetData the platform must pick a supported reset type to perform. The platform may optionally log the parameters from any non-normal reset that occurs. |
